Seeing the Grit Orchestra playing at Glasgow Concert Hall on the opening night of Celtic Connections. I was amazed at there being nine double bass players and four bagpipe players in the orchestra. I felt all the sound reverberate from my toes to my head.

Feeling at one with the moment and the feeling!

Yo Yo MA solo at Lincoln Center or Carnegie when I was about 9. My mother took me. It took my breath away. I had never been transported that way by music before.

listening to Steve Reich live for the first time, at Le Poisson Rouge.

Brooklyn Philharmonic with Spano conducting, and they performed something by Ligeti but behind a think screen. I could hear the subway softly rumbling from below.

Memory # 3. It's the all night marathon at World Financial Center. I've settled in for the overnight in order to hear Stockhausen‘s Stimmung at dawn, along with a few hundred other friends and like-minded strangers. Energy is lagging, people are nodding out in their seats. Then, at about 4 in the morning, Dan Deacon is set up in the middle of the venue, a few dozen fans in tow. He blasts out a noisy set of electronic punk rock, and for the first time I recall, there's crowdsurfing at a BOAC Marathon.

Memory #2: I think it was the first BOAC Marathon at Alice Tully Hall, 1997. I went to the restroom during a break, and when I came back, Icebreaker were already onstage playing Michael Gordon's Trance. I remember being stunned by the mix of minimalism and hardcore riffing, and being unable to take a seat - my memory is that I watched the entire hourlong piece standing in the aisle, transfixed.

3 memories. Will post separately Memore #1: Earliest one - it's probably the summer after my freshman year in college. I had just learned about Terry Riley's In C through a class in the Music of Frank Zappa. Found out that BOAC was presenting it at RAPP Arts Center, a converted school in what was then still referred to as Alphabet City. Somehow, I succeeded in convincing my musician father to join me in volunteering for the event, helping check tickets. My mind was continually cracked open for many hours. I don't think he even remembers it ;)
